To all whom, t may concern:

Be it known that I, EUGENE R. EDsoN, a citizen ofthe United States of America, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented lcertain new and useful Improvements in Apparatus for Separating Naphtha, dec., from Oil; and I hereby declare the following to beafull, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to makeand use the same'.

Hy invention relates to improvements in a-pparatus for separating naphtha or other readily-volatile matter from oil, and more especially designed for separating and eliminating naphtha from oil extracted from oilyielding material by the treatment ofthe said material with naphtha.

The object of this invention is to provide apparatus of the character indicated which is simple and durable in construction, which has a large capacity, which operates with facility, and whose component parts are readily assembled and as quickly and conveniently separated for repairs, renewal,`and cleaning.

With this object in View and to the end of realizing other advantages hereinafter appearing the invention consists in certain features of construction and combinations of parts hereinafter described, and pointed out in the claims.

Referring to the drawings, Figure I is au end elevation, largely in central transverse section, of the tank wherein the vaporizing of the naphtha or otheryolatile matter takes place, and this figure shows also the heat-'radiating plates and'other parts contained within the said tank. Fig. Il is a side elevation, largely in central section, of the said tank, and shows also parts within or connected with the tank. Fig. III- is a section in detail, showing a portion of one of the heads instrumental in supporting the heat radiating plates 'and illustrating more especially one of the ports formed in the said head and establishing open relation between the chambers of two adjacent plates of one of the series of heat-radiating plates. Fig. IV is atop plan in section andV in detail, illustrating the formation and arrangement of the port instrumental in establishing open relation between the heating-iluid-supply pipe and the chambers of the uppermost plat-es of both series oftJ heat-radiating plates. Fig. V is a top plan in section and iu detailillustrating the formation and arrangement of the port instrumental in establishing open relation between the chambers ot' the lowerlnost plates of both series of heat-radiatin, r plates and a'pipe employed to conduct Huid from the said chambers. Fig. VI is a side elevation of the aforesaid tank and connected pipes. Fig. VII is a view in perspective, illustrating three heatradiating plates and the -portions of the two heads between which the said plates are interposed; and Fig. VIIIis a side elevation in section, illustrating portions ot' the said heads and two intervening heat-radiating plates.

-Ret`erring to the drawings, a designates a cylindrical closed tank, which is arranged in a 'horizontal plane. Two vertical upright parallel or approximately parallel heads b and b are arranged within and a suitable distance 'apart longitudinally of the tank and preferably a short distance from opposite ends, re-

spectively, of the chamber of the tank. The

heads b are supported from the tank.

Two upright series of laterally and downwardly sloping heatradiating or heating plates c, respectively, having a correspondingly-sloping upper imperforate side, are arranged side by side and a short distance apart laterally between the heads b.- The two series of heating-plates o are arranged, therefore, in opposite sides, respectively, ofthe chamber of the tank. Each platee, as already indicated, slopes widthwise, but is arranged longitudinally in a horizontal plane between the twoheads b and preferably clamped at its ends by and between-the said heads, as will hereinafter appear. The plates of each series of plates o are arranged at diderent elevations, respectively, and slope downwardly in opposite directions alternately, and preferably the uppermost plate of each series of plates c slopes downwardly and outwardly, and the lower-most plate of each series of` plates c slopes downwardly and inwardly. Consequently each series of plates o comprises an even number of plates, and the arrangement of the parts is such that the uppermost plates of both series of plates o are arranged side by side and slope apart or diverge down- IOO wardly, that the lowerinost plates of both series of plates are arranged side by side and slope toward each other or converge downwardly, and that the upper side of each` plate ot' each series of plates except the lowermost plate slopes downwardly toward and discharges onto the upper portion ot' the upper side of a plate next below. Obviously, therefore, the plates ot' each series of plates c have such relative arrangenieut that the mixed oil and naphtha or other liquid which is to be heated within the tank o, and which is fed or conducted to and upon the upper side ot` the uppermost plate of the said series ot' plates will i'low by gravity successively adown the upper sides of the remaining plates ofthe said series of plates.

Each plate c is hollow or chambered interiorly, as at d, and the heating fluid employed in heating the said plate is conducted into the interior chamber ot' the said plate.

lSy the construction herein before described it is obvious that the-uppermost plates ot both series of plates c have their upper portions near each other, and one of the heads l) is provided, adjacent. to the said upper portions ot' the said uppermost plates o. with a port e, which (see Figs. I, lI, and IV) communicates with the chambers ot' the said plates, and the valved pipe j", whose valve g is normally closed, discharges into the porte and is employed to conduct steam, hot water, or other heating fluid to the said port.

The chamber d of each plate ot" each series of plates c except the chamber d of the lowermost plate of the said series of plates is placed in open relation (see Figs. l, Il, III, V, VII, and VIII) with the chamber d of the plate c next below by one or more ports 7L, formed in one or both of the heads b, and the chambers d, of the lowermost plates of both series of plates c communicate with a port t, formed in one ot' the heads l), as shown in Figs. I, II, and IV, and a valved pipe l has its receiving end communicating with the said port k and has its valve m normally closed. It will be observed, therefore, that upon opening the valve g steam or other heating fluid passes from the pipe f into the chamber Z of the uppermost plate of each series ot plates c and will successively pass into the chambers d of the remaining plates c of the said series of plates, and a circulation through the chambers ot' the said plates will be established upon opening the valve m as weli as the valve g.

Fluid-tight joints are of course formed between the ends ot' the plates c and the heads i); but packing of joints is too well known to require description o1' illustration in this application. The plates c are, however, snugly interposed between the heads b, which are caused to clamp the ends of the said plates by bolts n, and nuts o, which are suitably applied to hold the heads b and the intervening plates c tightly together. (See Figs. I, II, VII, and VIII.) The bolts n extend through the heads Z) and have their heads p bearing against the outer side ot one of the heads l), and the nuts o are mounted upon the Shanks of the bolts at and bear against the outer side ofthe other head b.

The means employed for conducting the mixed oil and naphtha or other liquid into the tank a comprises a valved pipe o', whose valve 10 is normally closed. The pipe r (see Figs. I, II, and IV) extends into the tank u, and discharges into a funnel l2, which is arranged over and centrally between the ends of and discharges into a perforated pipe 13, which is arranged above and extends longitudinally of the upperand. central portion of the upper side of a liquid-distributing plate s, arranged above and longitudinally of and overhanging the upper portion of the uppermost plate of each said series ot' plates c. The perforations 14 ot' the pipe 13 are arranged to discharge outothe upper side of the plate s, which slopes downwardly from in under the said pipe 13 in opposite directions, so as to conduct liquid flowing from the said perforations 14 onto the uppermost plate of cach series of plates c. Obviously, therefore, any liquid adapted to be supplied by the pipe a' is upon opening the valve 10 ofthe said pipe conducted to the perforated pipe 13 and by the latter discharged upon and along the dist tributing-plate 14 and by the said plate dis tributed upon the uppermost plates of both series of plates c. The pipe 13 is closed at its ends, as shown in Fig. II, so that liquid can only escape from the said pipe through the perforations 14.

The means employedor conducting the liquid which is not vaporized within the chamber of the tank a outside of the said tank comprises, preferably, a trough t, which (see- Figs. I and Il) is supported in any approved manner within the tank below the lowermost plates c. The trough t is closed at the ends and extends widthwise under the lower portion of the lowermost plate of each series ot' plates c and extends from end to end of the said lowermost plate, and obviously any liquid flowing or passing downwardly from the lowermost plate of each series of plates c gravitates into the trough, and a drain-pipe 16, whose receiving end is connected with and in open relation with the said trough, extends downwardly from the trough outside of the tank and is provided with a normally closed valve 17 externally of the tank. The tank a is provided also with a drain-pipe 18, arranged to drain from the said tank any liquid accumulating from any source upon the bottom ot' the chamber of the tank.

The tank a is provided (see Figs. II and VI) at the top with two vapor-outlets 20, which are arranged a suitable distance apart longitudinally of the tank, and a pipe to, arranged externally ot the tank, is provided centrally between the said outlets with two branch pipes 22, communicating with the said outlets. The pipe u is connected with the receiving end or inlet of a suitably-operated IOO lIO

pump 23. The operation of the pump 23 during the treatment of liquid within the tank ct obviously creates suction within the said tank and facilitates the passage of vapors from the tank.

The heads b have .lateral openings 25 between the two series of plates c at different elevations to enlarge the means of escape from between the said series of plates of vapors arising from the liquid passing adown the downwardly and inwardly sloping plates of the said series of plates.

Sometimesit is desirable to introduce steam and air into the chamber of the tank a to facilitate the elimination and escape of vapors arisingfrom the liquid heated within the tank,

and consequently several valved perforated pipes are arranged at different elevations, respectively, within and longitudinally of the chamber of the tank Ct between the two series of' plates c and extend outside of the tank, and are each provided externally of the tank with a normally closed valve 27, and are connected with a valved steam-supply pipe gj, whose valve 28 is normally closed, and with an air-supply pipe 30, whose valve 32 is normally closed. By the provision and arrangement of valved pipes rr, y, and 30 air or steam is conducted to any pipe n upon opening the valve 27 of the said pipe fr, according as the valve 32 of the pipe 30 or the valve 2S of the pipe g/ is opened.

A not unimportant feature is the provision of each plate c upon its upper side (see Figs. I, VII, and VIII) with an upwardly-projecting rim or ange 33, extending along all of the edges of the said plate except along the lower edge, adown which flows any liquid conducted onto the upper side of the said plate, which flange or rim extends transversely of the last-mentioned edge at the extremities of the said edge, and obviously by this construction liquid conducted onto the upper side of any plate c can only flow from the said plate adown the aforesaid lower edge, which slopes downwardly and outwardly to the under side of the said plate, and it will be observed also that the flange or rim 33 of each plate of each series of plates c, except the rim or flange of the uppermost plate of the said series o f plates, separates the upper side of the said plate from the next plate above and positively prevents any plate from making contact with the liquid-conducting upper side of a plate next below, and each plate c, which is arranged to discharge onto another plate c, preferably engages at its upper edge the flange or rim 33 of the last-mentioned and lower plate a short distance from the upper extremity of the last-mentioned plate.
